Oxazolinethiones and Oxazolidinethiones for the First Copper-Catalyzed Desulfurative Cross-Coupling Reaction and First Sonogashira Applications

Cyclic thionocarbamates, namely chiral oxazolidinethiones (OZT) and aromatic oxazolinethiones (OXT), were involved, for the first time, in Sonogashira cross-coupling. A cooperative effect of two different copper (I) speciesCuI and CuTCaccounts for this new copper-catalyzed desulfurative carbon−car...

Description
Summary:Cyclic thionocarbamates, namely chiral oxazolidinethiones (OZT) and aromatic oxazolinethiones (OXT), were involved, for the first time, in Sonogashira cross-coupling. A cooperative effect of two different copper (I) speciesCuI and CuTCaccounts for this new copper-catalyzed desulfurative carbon−carbon cross-coupling reaction. This cooperative reactivity could also be extended to other copper (I) catalysts.
